As of course was Big Brother’s plan all along, things well and truly kicked off last night when Heidi Montag and Spencer Pratt returned to the Celeb BB house after it was revealed that The Hills really do have eyes, and ears, and that Speidi had in fact been eavesdropping in the basement and hadn’t left the house at all.

And as we saw in last night’s live eviction show, during which Sam Robertson left, the housemates in the main house all shouted, “I knew it!” when Big Brother revealed Heidi and Spencer’s secret mission.

BB broke the news to the house while broadcasting Heidi and Spencer in the Diary Room as they nominated Claire Richards and Rylan Clark to face the public vote this week, adding that “there will be fireworks” over what they’d seen and heard while in the basement…

Spencer told Big Brother, “I can guarantee it’s gonna be fireworks because Speidi’s not playing. Just wanted to give you the heads-up.”

Heidi added, “They’re all jerks. They’re emotional vampires who just feed off each other but it’s gonna all end this weekend, little ones.”

Before he and Heidi left the basement, Spencer said of Rylan, “Rylan is the biggest fame-whore ever. He looks like a rat. And he has a fake nose.

“He reckons he going to sing a Spice Girls song on the X Factor tour. I feel bad for the audience. He will ruin it.”

Heidi said of Lacey Banghard, “She’s going bald and definitely had surgery.”

And sure enough, Speidi hadn’t been back in the main house more than a few minutes when those fireworks began, with Rylan being the first housemate to challenge Speidi on their claim that everyone was “mean spirited, nasty and fake.”
